Hello all. Curious what I should be using for closed loop intial values. I've done a bunch of research and from my understanding the idle should come back down gradually to idle and not dip below and have to recover, causing possible idle surge and stalling. I do have an extra row in my timing set a few degrees higher below idle at 500 to aid in recovery. Here's what I currently have set. I've played around a buch with the the idle valve, and have done some canbus test on the valve to see where it made the vehicle idle. Cranking duty for the stock basemap also have a flat line of 25.1. The motor is a 347 with 42 lb injectors. The base timing is set at 10. I have an X303 cam and heads with a GT40 intake. The motor usually has a KB flowzilla/blowzilla on it, but I removed to learn tuning. Quite a steep curve still even after a few months... coming from Anderson PMS and a A9P. Thank you for taking the time to read this.

Thanks for the bump! I located a91what's videos and got some better understanding. Everyone here probably was already thinking that. I'm a few years ate to the party but I think I got it sorted. Now I'm in between 2 and 4 squirts alternating per cycle. I removed my Kenne Bell upon install of the MSPNP to get a better understanding before I went back to forced induction to eliminate a variable. I have 280 150 558 42lb lightning injectors and thought my PW at idle might be too low at 1.8ms. So I changed to 2 squirt and now am around 3.2ms. Car seemed smoother at 4 squirts and might switch back, I am thinking I might be just outside the danger zone of those injectors at 1.8ms. Maybe someone will weigh in...
